The length of each section of the crash barrier in the car ramp section can be slightly longer, and the length of each section of the crash barrier in the outdoor corridor section should be slightly shorter due to its higher height.

[0036] Both step S2 and step S7 include: removing the concrete slab; removing the main beam; the removing of the concrete slab includes: drilling rope holes and lifting holes in the concrete slab; drawing cutting lines and cutting the concrete slab; lifting the concrete slab in sections; the removing of the main beam includes: drawing cutting lines, cutting the main beam once, and lifting it to the ground; cutting the main beam lifted to the ground into blocks for the second time; during operation, the rope holes and the rope holes are drilled with a diamond thin-wall drill, with a drilling depth of 200-250mm; the cut blocks need to be pre-lifted before cutting, and considering the capacity of the lifting equipment and the convenience of vehicle transportation, the weight of a single piece of concrete shall not exceed the upper limit of the capacity of the lifting equipment and the vehicle transportation capacity; the main beam cutting is carried out in the same way, and before the main beam is cut and separated, anti-tilting measures should be taken at the end cross beam to prevent instability.

[0037] The step S7 also includes: setting up an unloading support device under the outdoor corridor support plate; adjusting the unloading support device to uniformly support the support plate; the unloading support device includes: two bases, the bottoms of the two bases are fixedly provided with movable wheels that can be lifted and stored, the tops of the two bases are fixedly provided with height-adjustable support components, a distance adjustment mechanism is fixedly provided between the outer walls of the two bases, the support component includes a support rod and a hydraulic lifting platform fixedly provided on the top of the support rod, the top of the hydraulic lifting platform is fixedly provided with a force platform, and the outer wall of the support rod is fixedly provided with an elastically retractable L-shaped rod.

At this time, the L-shaped rod is clamped on both sides of the support plate, and the support plate is cut with the line connecting the two L-shaped rods as the cutting line. The cutting is also carried out along the line connecting the midpoints of the two force platforms, so that the cut concrete slabs are erected between adjacent force platforms without falling to the ground, ensuring construction safety while facilitating the lifting of the support plate.

[0038] Both step S3 and step S8 include: drilling a hoisting hole in the middle of the upper end of the support column; cutting from the root of the support column; hoisting the cut support column to the ground and cutting it into blocks; hoisting and transporting; during operation, the weight of the cut block support column shall not exceed the capacity of the hoisting equipment and the upper limit of the vehicle transportation capacity.
